Follow-up on the weak spark/coil issue. I got the new coil from Amazon,put it on and the engine fired right up,sounding better than it ever has. I went out and found the tallest grass I had around the yard and mowed for a half hour or so. I then restarted the engine several times while it was...

That is good info for me. I see on Amazon,they have the 590781 coil listed for a 42A 707,which is what I have. $15.00. Not a bad price,but a bit of a job getting to on this engine. Briggs didn't skimp on shrouding or number of bolts holding them on on this engine!

No,Shell Rotella straight 30W If you read the specs label,Rotella isn't recommended for gasoline(Spark) engines,but this is because the large amount of anti-wear additives ,mainly ZDDP,are not compatible with automobile engine catalytic converters. Modern car engines usually don't have flat...

I had a no start issue with the Twin 2 after it was up to running temperure after mowing for a half hour or so. It looked to me that the spark wasn't as hot as I thought it should be,as no spark that I could see. After it cooled overnight it fired right up,no problem. I mowed a bit and...

(Waaaay off from lawnmowers,but.....Back before I retired,a couple of the guys in the shop were bass fishermen. One was overheard to say,"I'm trading in my current outboard for a bigger one." The other guy asks,"Why?". First man says ,"I can't bust 100 MPH.". I thought to myself,"Man,those bass...

2 cycle usually,almost unlimited rpm.10,000 rpm isn't out of the question. Of course,Yamaha and Mercury are in a high 4 stroke horsepower competition now. 400+hp outboards are on the market right now. Of course,they come with a price tag that is HIGH also!! Still,I would have liked to have...

Thanks for the kudos! However,I'm way back in second place on this hop-up. I have looked and looked for the Snapper video that I saw a year or two ago with no luck. This guy put an outboard engine powerhead on a Snapper! As best as I can remember,it was 115hp Mercury outboard. It was...

If you look at my sort of jury-rigged muffler setup on the Snapper,the "chin" muffler works fine wired up the way I have it now. Two lengths of angle off the rear frame box will do away with the baling wire and look, well,morel finished. Just haven'y had the time or have gotten the angle iron...

Nope,it does not notice that clump of fescue! Of,course,the 17.5 Intek didn't either,but the opposed twin does seem to run smoother than the Intek single. That makes sense though,it's a naturally balanced design,unlike the Intek single that has all the extra parts to try to combat the inherent...

Not pressure-lubed. :-( As far as idling, as a matter of course, I run at recommended rpm,both for oiling and for cooling. I've read from many posters that poking around at low rpm hurts both the engine and the hydros. Briggs themselves,say let the governor do it's job and run at or near...

As I said in the previous post,2 different Intek AVS 17.5 singles have failed me,or should I say they broke themselves(and me,too,$$)! a couple of years ago,the first one ,for no good reason,snapped the head off a valve right above the stem and the head punched right through the piston. I bought...

Thanks for all the positive comments on the Briggs opposed 2 cylinder engine. I really wasn't wanting to spend major money on another Intek engine that seems to have inherent reliability issues. I know,I know,there are those that will sing their praises. That's ok with me,but I have had 2 that...
